non contiguous child domain

[Stubby]

All:

with Windows 2003 server, is it possible to have this:

blah.ads -> empty root domain
| |
ab.blah.edu cd.blah.edu -> 2 child domains of blah.ads, with different
names

Is this possible when the DNS (BIND) server resides in a blah.edu zone with
all of the records for both ab.blah.edu and cd.blah.edu? I can't find
anything definitive that says child domains can have different names than
the parent in a Windows 2003 AD environment. Thank you.

AD child domains also have the parent AD domain name in their name.
So if you have PARENT.LOCAL as a parent domain
a child domain would always be CHILD.PARENT.LOCAL. It cannot be CHILD.
SOMETHING.ELSE
The only solution for you to realize the names you want is to create
three different trees where each tree contains a root domain. That is
possible
The AD hierarchy is NAME hierarchy! There is not admin hierarchy or
whatever. Although you can only have on forest root domain, ALL
domains in a forest are equal and each admin in a domain must be
trusted!

ab.blah.edu and cd.blah.edu wouldn't be children of blah.ads, they would be
considered separate domain trees. In fact, that configuration would consist of
three trees including the blah.ads tree. A child domain follows the same
hierarchical naming structure.

It will still work fine for AD though some apps and scripts may have an issue
because not everyone properly codes for multiple trees in a forest and makes
assumptions on the namespace.

The DNS is completely separate, you would need zones for ab.blah.edu,
cd.blah.edu, and blah.ads. Preferably they should allow dynamic updates. However
for specifics on configuring DNS, hit the DNS newsgroups, many full blown DNS
experts there that can walk you through the BIND configs or whatever else.
